vulkan/wsi: untangle buffer-images from prime

Browse Source 
Not all Vulkan implementations allows rendering to linear images, so in
order to support scanning out from these on Windows we might have to copy
through a buffer like we do in the PRIME path.

To avoid reimplementing the same, let's instead generalize the code a
bit so it doesn't have to specfy any PRIME-specific details.
